FORT WORTH, Texas — Trevone Boykin threw a school-record seven touchdown passes and No. 10 TCU showcased a new fast-paced offense by scoring the most points in its history in an 82-27 rout of Texas Tech on Saturday.

The Horned Frogs (6-1, 3-1 Big 12) beat their previous scoring high of 69 in the spread attack directed in part by co-offensive coordinator Sonny Cumbie, a former Texas Tech quarterback who spent the past four seasons as an assistant with the Red Raiders.

Boykin had two scoring tosses each to Josh Doctson and Deante Gray, who had a 92-yarder about 2 minutes before Ty Slanina caught a 57-yard touchdown that gave TCU 61 points midway through the third quarter.

TCU scored the most points by an FBS school since Oklahoma State beat Savannah State 84-0 on Sept. 1, 2012.

Texas Tech (3-5, 1-4) rolled up 287 of the combined 512 total yards in the first quarter before fading with turnovers and special teams mistakes.

Boykin was 22-of-39 for 433 yards while setting a career high in yards passing for the second week in a row, this time needing just three quarters before he was replaced by Matt Joeckel.

The touchdown that put TCU over 70 points for the first time was a pitch from third-stringer Zach Allen to Trevorris Johnson for a 4-yard score two plays after Joeckel limped off the field.

Johnson scored again to put the Horned Frogs over 80 with 1:16 remaining a decade after Cumbie led the Red Raiders to a 70-35 victory over the Horned Frogs, the most points allowed in Gary Patterson’s 15 seasons as coach.

TCU, which beat New Mexico 69-0 in its previous highest-scoring game in 2011, topped the Red Raiders for the first time in three tries since joining the Big 12 in 2012 and reuniting the former Southwest Conference foes. It was TCU’s first win over Tech since a 12-3 victory in 2006.

TCU set a series scoring record against an opponent for the fourth straight week.

It was yet another payoff for Patterson after hiring Cumbie and Doug Meacham in the offseason when he decided that he needed an offense that could keep up in the fast-paced Big 12.

Texas Tech’s Davis Webb kept pace early by throwing for 230 of his 300 yards in the first quarter before an interception and two fumbles by the quarterback led to 13 first-half points for TCU. Webb was replaced by freshman Pat Mahomes after he was slow to get up from a hit in the third quarter.

Gray led TCU with 165 yards receiving on four catches, and Doctson added 76 a week after he missed the school record by a yard on a 225-yard day that included touchdowns of 77 and 84 yards. He had a 51-yarder this week.

Aaron Green had a career-long run of 62 yards for TCU’s first touchdown and finished with 105 for his first 100-yard game.

DeAndre Washington’s two-game streak of setting career highs in rushing ended with the Texas Tech running back finishing with 77 yards, including a 48-yard run that set up a field goal for a 10-7 lead in the first quarter.

After the last of four turnovers from the Red Raiders on an interception by Mahomes late in the third quarter, TCU’s Chris Hackett and Texas Tech’s D.J. Polite-Gray received offsetting personal foul penalties and were ejected for throwing punches. They will have to serve one-game suspensions.
